Design of IOT-Based Body Temperature Monitoring Prototype at Syekh-Yusuf Islamic University Tangerang Using Black Box Testing Method

The spread of the Coronavirus Disease (Covid-19) virus since 2019 has caused a pandemic in this world. Generally, the existing body temperature checkers only function to check the temperature, and allow someone to escape from the process. By utilizing the Internet of Things, it is possible to make a body temperature checking device that can measure measurement data into a database, and display it on a smartphone through an application and this tool is named the Design and Build of a Prototype of Internet of Things-Based Body Temperature Monitoring. The tool uses an infrared temperature sensor which functions to measure contactless body temperature and before using the sensor must be accessed using a Radio Frequency Identification (RFID) card so that data that has checked body temperature can be stored. The data is stored in a database and can also be accessed in the form of a website using the black box testing method. This method is used to find out if the software is working properly. With this tool the screening process becomes more leverage, because the tool can record the temperature of the user of the tool and can store it in the database.


INTRODUCTION
Technological developments have become very useful in the current pandemic conditions, implementing health protocols is one of the efforts to prevent the spread of the Covid-19 virus.Body temperature is an indicator for people with Covid-19 symptoms.Measuring body temperature is a way to avoid cases of spreading this virus.
In practice, checking body temperature at the Syekh-Yusuf Islamic University in Tangerang is only carried out manually by monitoring the temperature checking machine and there is no data that displays the student's body temperature.This allows students with inappropriate body temperatures to pass the screening.
Testing will be carried out using the black box testing method, the black box testing technique only focuses on the information domain of the software.This research is only to measure the radiation (coverage) range of the sensor by placing the sensor in a place that is not blocked by any objects, and directing it to the object (human) to be detected.The results obtained from the sensor's transmit power coverage with various height variations show that the maximum emission is at a sensor height of 150 cm from the floor.A distance of 5 cm is the furthest point for detecting humans.
Therefore, the author is interested in creating a body temperature monitoring prototype design that can check body temperature and also collect data automatically so that the possibility described previously can be avoided.With this tool, it can help students to carry out checks without coming face to face with people who want to enter the classroom, this prototype detect body temperature remotely.In this case, management determines that people who want to enter the classroom above 37.5°C are not permitted to enter the classroom.
The materials and tools used in this research are Black Box Testing, Microcontroller, MLX90614 Sensor, ESP8266, Arduino Uno, Atmega IC, RFID Reader, Buzzer, OLED LCD, 16x2 LCD with I2c.

RESEARCH METHODS
In data collection methods to obtain information I use several methods including: 1) Observation, this method is carried out directly by researching and collecting data at the Syekh-Yusuf Islamic University, Tangerang, precisely on Jalan Maulana Yusuf No.10, Babakan, Tangerang District, Tangerang City, Banten 15118.2) Interview, interview was carried out by communicating with the data source.This communication is carried out through verbal question and answer dialogue.3) Analysis Method, In developing a prototype that suits the user, the author uses methods from data and tool performance results that are in accordance with the aims and objectives of making the tool.From the resulting data, researchers carried out analyzes to determine the parameters for the success of the tool.
In Design Method, the design of the device here plays a very important role because it is necessary for the operation of the tool to be made.Device design is divided into several things, namely: 1. Main Program Design.2. Database Design.3. Software Design.

Initial Observation
The initial observation stage is the initial stage where the researcher carries out several observations to determine several things that can be used as research.

Identify the Problem
At the problem identification stage, researchers discuss problems that may occur in the research process.At this stage, after initial observation, of course several problems will arise, such as when checking body temperature by humans, then to minimize direct contact between people, because direct contact can make the spread of this virus faster and also the implementation of health protocols that have not been monitored so that It is not known who has carried out the health protocols.

Identify Solutions
At the solution identification stage, researchers look for ways so that each problem that emerges can be resolved.Discussion between researchers is a method for identifying solutions to problems that may occur.In this research, researchers created a tool to monitor health protocols and also reduce direct contact between people so that the spread of the virus can be avoided.

Determine goals
At the stage of determining the goal, after finding a solution to the existing problem, the researcher begins to design the goals that will be achieved, the goals that the researcher will achieve include maximizing efforts to prevent the spread of the virus, knowing data on the implementation of health protocols, and designing tools to avoid the escape of people with symptoms.Covid-19 entered campus.

Library and Literature Study
At this stage, the researcher looks for library studies and literature to find a reference that has already been carried out in further research, and is also related to the research being carried out.6. Creation of Work Sequence 1.The design of the device here plays a very important role because it is necessary for the operation of the tool to be made.Device design is divided into several things, namely: a. Main Program Design This is an algorithm for all program running processes on the body temperature measuring system hardware using the MLX90614 sensor which is programmed by the ESP8266.The first step begins with initial initialization of analog ports, input/output, RFID.Where in this situation the temperature sensor is not working.If RFID has detected a registered card, the MLX90614 sensor will be active and ready to measure the temperature of the object, however if the card is not registered you can still check the temperature, but the data will not be saved to the database.If the object's temperature is detected, the ESP8266 will save the data into a database and the temperature measurement results will appear on the 16x2 LCD.If the object temperature exceeds 37oC the buzzer will sound for 1 second.

b. Database Design
The database is used to store users who have used the tool by containing temperature data, user name and blood oxygen levels if the user's temperature exceeds 37oC.This data is stored in a database for further use by the software.c.Software Design After obtaining the data from the user's measurements, the temperature data, user name and oxygen level in the blood are uploaded into software so that it can be seen and accessed by anyone who has used the tool.d.Tool and Software Design At this stage, the researcher designs the tools and software after all the data has been obtained and has been processed, determines this design also by considering field conditions for the placement of the tools.

e. Results and Analysis
At this stage, the researcher obtains the results of the tool that has been created and obtains data and results of the tool's performance in accordance with the aims and objectives of making the tool.From the resulting data, researchers carried out analyzes to determine the parameters for the success of the tool.
